Abstract

A system and method is described for effective management of a User Interface (UI) of a wireless device by implementing direct mapping between the application data domain and UI screens and controls. The device has an intelligent wireless device runtime environment (Device Runtime) that provides a set of basic services to manage the wireless application, including a series of linked screen and data component definitions, and their interactions can simplify the development effort and reduce resource allocation. The data domain for this category of applications is defined using the atomic data component definitions. The communication between a device user interface and data components is defined using atomic screen component definitions. Both screen and data component definitions are described in metadata using a structured definition language such as XML. The relationships between the screen and data component definitions are embedded in the XML definitions in the form of screen/data mappings. Typically, rendered screens for display are derived from some underlying data component and screens controls affected by user events impact the current state (or data representation) of the application Changes to the application domain data are automatically synchronized with the user interface, and user-entered data is automatically reflected in the application domain data. The primary mechanism behind this synchronization is the mapping of screens and data. This mechanism enables creation of dynamic and interactive screens. All changes to the data component can be immediately reflected on the screen and vice versa. This model allows building effective wireless applications based on server-to-device notifications. The data updates asynchronously pushed from the server are instantaneously reflected at the UI screen.

With reference to figure 3,8 and 9, the connectivity between contact manager 306 management application programs 302 and the external system 10 is for example represented message 105 and the related data of application program 302 at network service 106 (by contact manager 306) transmission/reception.As described below, can use contact manager 306 to realize a string mapping 804.When on the output device of user interface 202, exporting at that time the expression (see figure 2) of expression manager 308 management application programs 302.Data management system 310 allow component applications 302 with data storage in the memory module 210 of device infrastructure 204 (see figure 2), should recognize that manager 310 can be used for by shining upon 804 modification/establishments of coordinating the data instance of the data package 400 that links with screen assembly 402.Framework 206 also has map manager 312, is used to follow the tracks of each relation (mapping) 804 between each data object 800 and the screen elements 802.Mapping is stored in the mapping table that links to each other with map manager 312.In case on user interface 202 initialization screen elements 802, represent that then manager 308 uses map manager 312 to keep the screen elements 802 that is shown and the dynamic integrality between the respective data object 800.When revising one of screen elements 802 by the user by user interface 202, map manager 312 is responsible for changing by data management system 310 and is propagated into proper data object 800 in the storer 210.During one of data object 800 in revising storer 210, map manager 312 is checked object 800 current whether being presented on the user interface 202, if like this, then be responsible for upgrading corresponding screen elements 802 by expression manager 308, by consulting the corresponding mapping 804 in this table, this variation is reflected in the data object 800.Should recognize that the framework services 304 of communication facilities 100 provides function to component applications 302, described application program 302 comprises above-mentioned manager.

Therefore, framework 206 allows to show interactive application 302 on user interface 202, and typically, expression is from the information in application program 302 territories and allow the user to import and revise related data object 800 and screen elements 802.Described framework 206 provides a kind of system that user interface 202 is effectively managed by realize directly mapping 804 between application data territory (data object 800) and UI screen elements 802 (for example UI control).The change of application programs numeric field data object 800 is dynamically synchronous with user interface 202, and user input data automatically is reflected in the Application Domain data object 800.Main mechanism after this is synchronous is the mapping 804 between paired screen elements 802 and the data object 800.Described mapped system relates to the wireless applications 302 of utilization with the meta data definition of expressing as structure languages such as XML.804 mechanism of shining upon can be created on user interface 202 dynamically and interactive screen.Institute to data object 800 can be changed synchronously is reflected on the user interface, and vice versa.Mapping 804 realization is convenient to notify to equipment according to server and is constructed wireless applications 302.UI screen elements 802 by link will synchronously be reflected on the user interface 202 from the data object 800 of server asynchronous push.These mappings 800 can be suitable for various wireless applications 302, and for example stock exchange, new renewal, warning, weather upgrade.

Application component

With reference to figure 2, carry out client application 302 in the environment constantly at the terminal operating of framework 206, and this application program support is to the visit (see figure 1) by the service 106 network service operations that provide.WSDL and soap protocol definition clearly comprise the message pattern.In the WSDL network service definition, utilize the notion of message and data division to define these operations, described message and data division are used for network service client terminal application program 302 is defined as the set (see figure 4) of related data 400 and message 404 assemblies.

With reference to figure 4, the block scheme of component applications 302 comprises data package 400, expression assembly 402.Residue message/workflow the part 405 of application program 302 can be provided by message components 404, described message components 404 by 214 coordinating with communicating by letter of execution environment 300, perhaps can it be set to the hard coded element 405 (as by with defined with program developer) of application program 302 by workflow component 406.Can the utilization structure definitional language assembly 400,404 (and if having used 404) be configured to series of metadata records, constitute by a plurality of predetermined-elements of specified attribute of expression resource, thereby each element can have one or more values.Typically, each metadata schema has the feature of definition, as but be not limited to: the implication of the element of limited quantity, the title of each element and each element.The example meta data plan comprise as but be not limited to Dublin kernel (DC), Great Britain and America and edit and record rule (AACR2), government information finger URL service (GILS), coding filing and describe (EAD), IMS whole world learned academy (IMS) and Government Of Australia finger URL service (AGLS).The coding grammer allow by device infrastructure 204 (see figure 2)s come processing components 400,402 (and if use, 404) metadata, and code scheme comprise as but be not limited to XML, HTML, XHTML, XSML, RDF, machine readable is edited and recorded (MARC) and multipurpose internet mail expansion (MIME).

Refer again to Fig. 4 and 8, data package 400 has defined the data object 800 that is used by component applications 302, comprises the application data of representing with as local code or XML.The example of the data object 800 that data package 400 can be described is order, user and financial transaction.Data package 400 has been described data of description object 800 to be needed any information and what form to express this information with.For example, data package 400 can define as but to be not limited to form be that bulleted list, the time with establishment order of date time format, the form of string is the order status of string and has another the user who orders of the corresponding to form of definition with data package 400 for the only identifier by at the order order, the form that constitute of numeral.Because the rules of arrangement (choreography rule) according to network service 106 is delivered to message 105 with data division (element) from message 105 usually, therefore preferably, has the continuation of data object 800.Can serve 106 layout definition (if available) according to network and dynamically produce data object 800, perhaps come definition of data object 800 according to the definition and/or the message relevant information of complicated type by application designer.Should recognize, can screen assembly 402 be mapped to data package 400 (see figure 9)s by shining upon 804, as described below.

In addition, described data package 400 can by as but be not limited to a string data field definition that HTML, XHTML and XML and other structure definition languages write and constitute, wherein data object 800 (see figure 9)s are the data instances according to the data field definition.Should be noted that the data object definition provides the definition of structure He its corresponding data type of data field, thereby data object 800 is examples of certain data objects definition.Data field comprises that data object definition and each data field have the related data type.In addition, the complex data field comprises the structure of subdata field.The data package 400 that the definition of data object 800 is included in application program 302 in the works.These data definitions are provided for defining the data model by application program 302 employed data objects 800.Therefore, data package 400 is and set of a plurality of data field definition combining, the form of definition respective data word segment value when with box lunch the example being turned to data object 800.400 definition of described data package can maybe can be selected via main or composite key and need not key word it is defined.These key words can use to be provided as the only link between right mapping (enum) data 400 and screen 402 assemblies with mapping 804.

Refer again to Fig. 4, expression/screen assembly 402 has defined outward appearance and the behavior by the shown application program 302 of user interface 202.Carry out when mutual when the user uses user interface 202 and component applications 302, described expression assembly 402 can be specified GUI screen and and control and the action that will carry out.For example, when the user to typewrite input or when pressing the button of edit box, the action that expression assembly 402 can define screen, label, edit box, button and menu and will adopt.Most of network service consumers use network service operations results' visual representation, therefore provide on can its equipment 100 of explicit user interface screen the time of running environment.

The example application program 302 that will illustrate to screen assembly 402 below and be used to accept transmit the screen assembly 402 transmission parameters of parameter.Consider that this application program has:

Data package 400 " User ";

List the screen assembly 402 " srcALLUSERs " of the choice box of all user names, had the button/menu item that shows the selected user details;

Demonstration is as the screen assembly 402 " srcUSERInfo " of user's details of parameter transmission.

Example XML data package 400

The data package 400 " User " that can use following metadata to define to have main key field " name ":

<cData?name＝″User″pkey＝″name″><dfield?name＝″name″type＝″String″/>

<dfield?name＝″street″type＝″String″/>

<dfield?name＝″city″type＝″String″/>

<dfield?name＝″postal″type＝″String″/>

<dfield?name＝″phone″type＝″String″/>

</cData>

Example XML represents assembly 402

" srcALLUSERs " screen cut and paste is mapped to the selection control " cbNames " of " title " field of all examples of " user " data package 400.The screen meta data definition comprises button or menu item, has with the selected parameter " user " that is delivered to user interface 202 as parameter to come display screen " srcUSERInfo ".

<cScr?name＝″scrAllUsers″>

…

<choice?name＝″cbNames″mapping＝″User[].name″/>

…

<action?screen＝″scrUserInfo″param＝″cbNames.selected″/>

…

</cScr>

Screen " srcUSERInfo " has defined the editor's control " ebName " on " name " field of the particular instance that is mapped to " User " data package 400 that transmits as parameter:

<cScr?name＝″scrUserInfo″param＝″User″>

…

<edit?name＝″ebName″mapping＝″User.name″/>

…

</cScr>

Refer again to Fig. 4, can the residue message of application program 302 and other workflow parts 105 usually be set by 302 yuan of hard coded application programs, and/or can it be set to the other assembly 404,406 described respectively with structure definition language and code/script.Under the situation of using atom message components (atomic message component) 404, these have defined by component applications 302 and have made the form that is used for the message 105 that communicates as external systems such as network services 106, and comprise the message data of representing with as local code or XML.For example, one of message components 404 can describe as but be not limited to order the message of the order of the only identifier that comprises order, the state and the note relevant of order with order.Can represent (with being mapped to) WSDL message with message components 404 definition that structure definition language is write onlyly, and can dynamically produce in the time of running.Therefore, according to the standard network service metadata of the definitional language that is used to express network service interface, as but be not limited to WSDL and BPEL, realize dynamically producing at the component definition and the related data content of client application message 105.Definition web service messages 105 in operating environment, and defined correlativity between the message components in the definition of component applications 302 404.Can use predetermined message parameter and/or realize this correlativity, as following further definition by independent workflow component 406.

Refer again to Fig. 4, under the situation of the atom workflow component 406 that uses component applications 302, these have defined processing that occurs or the action that will carry out when message 105 arrives (see figure 1) from system 10 in the time will carrying out action (for example, above-mentioned action by 402 appointments of expression assembly).Can define expression workflow and message 105 processing by workflow component 406.With workflow component 406 with programming language or the script writing strings of commands, as but be not limited to the ECMA script, and can be compiled as local code and carry out, as mentioned above by execution environment 300.The example of workflow component 406 can be given data assignment, function screen or be sent message 105.Workflow component 406 is supported the correlativity between the message 105 and has been defined application flow, as one group of rule of operation on other assemblies 400,402,404.To define many workflow components at the application program 302 that provides.

Usually, ECMA (European computing machine make NAB National Association 0f Broadcasters) script is the script of standard, and wherein script is called as by another program but not the instruction sequence that computer processor is explained or carried out.Other examples of some of script are Perl, Rexx, VBScript, JavaScript and Tcl/Tk.Usually, these scripts are indicative language, are used to operate, customize and make the facility robotization of existing system, and for example equipment 100.In such system, useful function becomes available by user interface 202 (see figure 2)s, and script is that function is exposed to programme controlled mechanism.According to this mode, equipment 100 is used to provide the object of finishing the script ability and the main frame environment time of running of facility.

Exemplary components 404,406 based on the application program 302 of assembly can be:

Example XML message components 404

<msg?name＝“ordConfirmation″type＝”response”

action＝“mhConfirmation″>

<part?name＝“orderId″type＝″String“/>

<part?name＝“status″type＝″String“/>

</msg>

…

Example ECMAScript workflow component 406

<actions>

<function?name＝”mhConfirmation”>

key＝ordConfirmation.orderId；

order＝Order.get(key)；

order.orderStatus＝ordConfirmation.status；

scrConfirmation.display(order)；

</function>

…

</actions>

Use XML or derivation come expression data 400, message 404 and represent 402 assemblies and use the workflow component 406 of ECMA script or its subclass can allow application developers to extract network service client terminal from any specific platform or environment, and realize the application program of " exploitation once moves Anywhere " in theory.How following example can utilize structure definition language (for example but be not limited to XML) and platform-neutral script/programming language (for example but be not limited to the ECMA script) if showing, definitions component is expressed network service client terminal application program 302.

In addition,,, can see that message components 404 can the relaying desired data, so that input and output message 105 as above given with reference to figure 4.The storage of the data in memory module 210 (see figure 2)s of corresponding data assembly 400 Mediation Devices 100 is so that represented on user interface 202 (see figure 2)s subsequently by expression assembly 402.Workflow component 406 can coordination data 400, the data transmission between the expression 402, message 404 assemblies.The client can directly store and upgrade atomic data object 800 time of running.

Example basic operation based on the Application models of assembly

Should be noted that with reference to following Fig. 9,10 and 11 and describe the operation that describes processing mapping 804 in detail.

With reference to figure 1,3 and 6, for example, operation 900 shows when equipment 100 receives the response message 105 that comprises message data (902), and suitably workflow component 406 is explained the data content (904) of message 105 according to suitable message components 404.Then, workflow 406 data streams (906) also are inserted into corresponding data assembly 400 (910) with data, so that be stored in subsequently in memory module 210 (see figure 2)s (912).In addition, if desired, workflow component 406 also is inserted into data suitable expression assembly 402 (908), so that show (914) subsequently on user interface 202 (see figure 2)s.

With reference to figure 1,3 and 7, operation 1000 show at as press the button or the data input 1002 of the action of choice menus item, the user carries out these actions (1003) by user interface 202 on user interface elements.Relevant workflow assembly 406 is explained input data (1004) and is created the data entity (1006) that is defined by suitable data package 400 according to suitable expression assembly 404.Then, described workflow component 406 is filled customer-furnished input data (1010) to data package 400, so that be stored in subsequently in memory module 210 (see figure 2)s (1012).In addition, workflow component 406 also will be imported data and be inserted in the suitable message components 404 (1008), send to network service (1014) in the message 105 so that will import data subsequently as data entity, as defined by message components 404.

In aforesaid operations, should recognize that if be included as the hard coded part 405 of application program 302, then the operation of workflow 406 and message 404 assemblies will correspondingly be other operations.

Predetermined and active screen produces

Wireless applications 302 can have the predetermined set of screen elements 802 and data object 800, in the application programming stage, and the relation (mapping 800) in the Field Definition of data package 400 and screen assembly 404 between these set of identification.This model can be called as predetermined screen and data relationship model, expresses with metadata in component field definition to screen elements 802 that the user represents and the mapping 804 between the data object 800 thereby can use as structure languages such as XML.

Can also dynamically produce the screen of user interface 202 according to the structure of the data object 800 relevant with screen elements 802.In some cases, can not predict the form (for example returning network service 106 operations of arbitrary XML) of the data stream that receives as input by message 105 (see figure 1)s in advance from server (network service 106).Under the situation of the data stream of representing with architecture to receive (for example XML), equipment 100 can be used the interpretative rule of definition by framework 206, screen format (for example UI control, layout etc.) is carried out intelligent predicting, so that the data object 800 that expression is represented by data stream.This can realize in the following manner: the XML in the manipulation of data stream (for example) node is to make up corresponding data sets part 400, then, corresponding data sets part 400 is explained with by distributing corresponding screen elements 802 by the framework 206 best bit-mapped on-screen assemblies of determining 402 by described map manager 312 (see figure 8)s, thereby is handled the data content of the data stream after the conversion.At exploitation wireless applications 302 be used for the data stream based on plan is converted between the even date of the component definition form of better being understood by the developer of map manager 312 and transformation rule, the plan of XML content will be scheduled to.This transformation rule will and be designed for the most common XML that runs into of conversion (for example) structured data stream content as the part of map manager 312.And the user can have the chance of upgrading the UI field and revise data before it having been stored into equipment 100 or having sent it back server.

Following example shows the arbitrary XML data stream segment of XML plan:

<dataNode1?attr1＝’val1’attr2＝’val2’>

<subDataNode1>abcdefg</subDataNode1>

<subDataNode2>222</subDataNode2>

<subDataNode3>333</subDataNode3>

</dataNode1>

<dataNode1?attr1＝’val1’attr2＝’val2’>

<subDataNode1>hijklmnop</subDataNode1>

<subDataNode2>555</subDataNode2>

<subDataNode3>666</subDataNode3>

</dataNode1>

Map manager 312 use comprise the data field definition, by the plan definition that application developer provided,

<dataEntity?name＝’dataNode1’>

<dfield?name＝’subDataNode1’type＝’String’/>

<dfield?name＝’subDataNode2’type＝’int’/>

<dfield?name＝’subDataNode3’type＝’int’/>

</dataEntity>

And dynamically use transformation rule so that the XML data stream the acceptable form of application program (according to the plan that provides) is provided and produces suitable XML data object 800:

<dataEntity?name＝’dataNode1’key＝’0’>

<dfield?name＝’subDataNode1’>abcdefg</>

<dfield?name＝’subDataNode2’>222</>

</dataEntity>

<dataEntity?name＝’dataNode1’key＝’1’>

<dfield?name＝’subDataNode1’>hijklmnop</>

<dfield?name＝’subDataNode2’type＝’int’>555</>

</dataEntity>

The expression of data object on user interface

When obtaining the screen of user interface 202, need be to resolving for bit-mapped on-screen element 802 shown data objects 800.The different options of certain data objects 800 that parsing will be used for initial value is as follows:

Initialization based on screen parameter

Typically, the data object 800 of data package 400 of value that will have bit-mapped on-screen element 802 is delivered to the screen of user interface 202 as parameter.In above given exemplary screen assembly 404, screen " srcUSERInfo " receives user's data object 800, as described parameter.Screen elements 802 on this screen in the data field definition that is mapped to user data assembly 400 will show from the data value in this parameter.

The initial value of Xie Xiing not

If at screen cut and paste shine upon 804 but also do not resolve the primary data object 800 of related data assembly 400, then will not show primary data value at the screen elements 802 that shines upon.An example will be that the screen at new user's data value is imported in definition.Initial user data package 400 will be also uncorrelated.After the user will newly be worth the data field that is input to screen elements 802, use mapping definition to create the new data-objects 800 of this data package 400, as following will be at user data update described.

The tabulation of all data objects

For the selection control/list type of screen elements 802, mapping 804 can be specified the data object 800 that will use all establishments, shown in above given exemplary screen assembly 404.

Screen representation

With reference to figure 3,8 and 9, this scene 850 has been described when drawing new screen on user interface 202 at the performed step of screen elements 802.In step 852, described map manager 312 detects the screen elements 802 that is mapped on data package 400 fields.In step 854, map manager 312 checks whether the data object 800 of the type is affixed on the screen-promptly as the parameter transmission.If like this, then map manager is delivered to expression manager 308 so that show it on screen in the data field value of step 858 place retrieve data object 800 and with it.If not so, then in step 856, on screen 202, show default value (for example screen blank, numeral 0 etc.) at this field type.

Control to the data renewal

With reference to figure 3 and 8, according to mapping 804 metadata, the value that the user is imported is reflected in the field value of the related data object 800 in the storer 210.

Described processing can relate to following function:

Input validation;

Data creation;

Data Update.

Input validation

The checking of user input data can be automatically based on data cmp (for example telephone number).

Data creation

According to input value,, then can create new data-objects 800 if run into the new data key value.In above given sample data assembly 400,, then create new user data object 800 if import previous undefined title.

Data Update

Result as the input of the user on user interface 202 can upgrade the field value at the data object 800 of available data assembly 400.

Upgrade operation

Dual mode more new model can be operated according to following dual mode:

Automatically submit to

When frameing out, the user submits data to.

The translative mode of management

Mapping specifies menu action (screen elements 802) with deal with data.For example, for many order screen, in the end " submission " menu item on the screen will upgrade/create result data object 800.Another menu item (for example " cancellation ") may cause importing abandoning of data.

With reference to figure 3,8 and 10, following scene 870 has been described the user input data on the user interface 202 (customer incident) has been mapped to flow process on the data object 800.In step 872, when the user on screen elements 802, import/more during new data, UI manager 308 is delivered to map manager 312 with described numerical value.In step 874, if this is the screen elements 802 of mapping, map manager 312 is resolved suitable data package 400 and requested data object 800 from data management system 310.In step 876, data management system 312 checking is mated with data package 400 field types that this screen elements 802 is mapped on it at the numerical value of screen elements 802 inputs.In step 878, data management system 310 is kept at the data value of revising in the temporary storage, and does not submit to-" dirty (dirty) " data.Data management system 310 is also resolved the renewal that this is an available data object 800 or the establishment of new data-objects 800.In step 880, customer incident is defined as submitted (option A) or is ended (option B).Definite for what submit to: option A: submit to,

1) user selects to be mapped to button or the menu item of submitting in the action (screen elements 802);

2) UI manager 308 is notified this action to map manager 312;

3) map manager 312 request msg managers 310 are submitted to and are changed;

4) data management system 310 is submitted this variation to and data object 800 is stored in the storer 210.

Definite for what end: option B: rollback,

1) user by selecting is not mapped to button or the menu item (screen elements 802) of submitting to action to be and frames out;

2) UI manager 308 is notified this action to map manager 312;

3) map manager 312 request msg managers 310 rollbacks should change;

4) data management system 312 abandons that this variation-this can represent: if created new mapping as screen assembly 402 to the result of data package 400 mappings 804, then only abandon the variation of each field or delete whole data object 800.

The control data updated

If equipment 100 can receive Data Update asynchronously from external source (for example network service 106), then will cause utilizing the screen-refresh of fresh information to the change of the data value relevant with screen elements 802.With reference to figure 3,8 and 11, when receiving message 105 from server 106 (952), message manager 312 determines whether message 105 are mapped on the data package 400 of the current executive utility 302 in the framework 206 (954).In this case, and then carry out following further step: in step 956, device framework 206 receives the notice relevant with data variation from server 106; In step 958,310 pairs of data objects of message manager 306 notification data managers 800 are carried out any relevant Data Update; In step 960, message manager 306 is also notified this data variation to map manager 312; In step 962, utilize mapping 804 metadata, whether map manager 312 verification msgs change relevant with current screen; In step 964, if variation is relevant with the information of current demonstration, then map manager 312 is asked UI managers 308 clear screens; And, refresh the data object 800 of this screen with display update in step 966.Otherwise in step 968, message 105 can not influence the currency of the screen elements 802 that shows on user interface 202.

Although disclose at one or more ultimate systems and method, many variants are apparent to one skilled in the art, and such variant is in the application's scope.For example, although the subclass of XML and ECMA script has been provided in the example that is provided, can also use other language and language variant to come definitions component application program 302.In addition, should recognize,, the definition of data field can be included in screen assembly 402 (see figure 4)s as a kind of selection of above-mentioned mapping 804.Therefore, the generation of screen elements 802 will define based on the data field that is included in screen assembly 402 definition, and data package 400 can be mapped on the corresponding screen assembly 402 with included data field definition (804).Therefore, the generation of data object 800 will depend on the data field definition that is comprised in the bit-mapped on-screen assembly 402.
